Chapter 1: Biology, Exploring Life
Govan Pahad
, Chapter 1: Biology, Exploring Life
• Important themes in biology
– Properties of living organisms; Levels of
organisation; Cells; DNA; Form & Function
• Evolution & diversity
– Theory of evolution; Classification of life’s
diversity; The story of life
• The process of science
– Experimental design; Scientific method
, The 7 Properties of living things
1. Order
2. Reproduction
3. Growth and development
4. Energy processing
5. Response to environment
6. Regulation of internal environment
7. Evolutionary adaptation
, Order All living things are
made up of organised
parts.
e.g.: Cells are
organised to form
skeletons, muscles &
organ systems in
humans; or
roots, stems & leaves
in plants.
Even a single-celled
amoeba has
organelles.
Picture: Sunflower illustrating the highly ordered structure that typifies life.
